This is a beautiful hack.
Because terrific work causes us to think of additional questions, I'd add: The only thing I found missing is that there is more than one polarization. So to accurately map the field, you'd need to perform multiple scans, with the receiving antenna rotated 90 degrees for each one.

Another question: when he uses the CNC to move the sensor around, isn't he also changing the reflective surfaces in the environment? Would this not produce inaccuracies?
